some time system admin need to disable or change the start up type of some important services on windows.If the windows Machines  are less than 10 we can manage but what will be if the count is more than 100?

Set-Service -Name "W32Time" -StartupType "disabled" -ComputerName (Get-Content C:\Computers.txt)

where computers.txt contains list of servers which we need to disable service..

It helps in saving lot of time..
